Canada's tornado warning system

Environment Canada is responsible for warning the public when conditions exist that may produce tornadoes. It does this through radio, television, newspapers, its internet site, as well as through its weather phone lines.

If you live in one of Canada's high-risk areas, you should listen to your radio during severe thunderstorms.
